How do you Solve a Rubik's Cube?

Solve it by layers, not by colors. It's pretty damn near impossible to solve by colors. The first two layers are easy, but the third one involves memorizing multiple algorithms. Stereo's method I've seen before in solving around the 2x2x2 block, but I never really understood it.

This is how I do it...layers is easy

I'm still really slow though...I used to be able to do it in 1 minute average but I haven't done one in quite a few months so it's probably slowed down to 2-3 minutes.
